I actually have little experience here - only as a browser. They do seem impressive though. What makes it a bit of a challenge is that it can be difficult to get into the place. Or maybe that is just me.
You walk up to the front and... you really have no idea which way to turn. One way you go into what appears to be a showroom, and the other way looks about like a showroom, but it has people working. Yes, the garage/service area is really that clean.
Eventually, we found our way into the showroom area, and we were not scolded too badly for our mistake. Then we noticed that either this place specifically or Harley generally is making a killing - or attempting to do so - on merchandise, because there is at least as much space dedicated to selling clothing of all sorts as there is to motorcycles. Not saying that is a bad thing, just that it is.
All-in-all, not a bad experience, and we really could not offer much up other than as browsers (even on the clothes side). Definitely worth a trip just to check out the place.
